【摘要】 用调Q红宝石激光和几种有机液体分子的受激喇曼散射—阶斯托克斯辐射作为泵浦光,射入钾蒸气中,观察到钾原子的许多非线性光学效应。如四波混频、增强的双光子跃迁、相干反斯托克斯幅射等。本文对这些谱线产生的机理、条件作了初步的探讨,并用温度调谐红宝石激光频率的方法对其中一些谱线作了较确切的判定。更多还原

【Abstract】 With Q-swiched ruby laser and ruby-generated stimulated stokes radiation in several kinds of liquids entering potassium vapor, some nonlinear optical effects were observed, such as four-wave parametric mixing, enh(?)nced and stimulated two-photon emission, stimulated antistokes radiation, etc.This paper primarily investigated and studied the reasons and conditions of generating of these spectra, and distinguished some of the lines by variation of the laser frequency changed with temperature of the ruby.更多还原
